Title: Optically inspecting method for storage disk
Inventor: YOSHIYAMA RYUICHI
IPC: G01N21/95
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To shorten inspection time, by receiving diagonally incident light with a light receiving element at a position where the light axis is shifted by specific angle, and detecting a defect on the basis of generation time for a signal whose strength is higher than a given level. SOLUTION: Incident light 4 is radiated from a light source 3 to an inspection surface 1a of a storage disk 1 at angle of 10-40deg. in relation to its vertical line. A light receiving element 8 is preferably placed at a position whose angle with the light axis of the incident light 4 is 10-40deg., because scattering strength for a defect is larger. When there is a circular defect to be detected, the light receiving element 8 receives power higher than a specific level for a specific time. The threshold level depends on quantity of light for the light source 3, sensitivity of the light receiving element 8, and signal amplification factor of a signal processing circuit 9, and is determined according to defect level to be detected.  Thus, because a circular long defect is detected in a condition more similar to that of magnetic inspection, inspection time can be shortened without reducing disk quality.

IPC: H04B10/50
Filed: 1990-10-01
Abstract: PURPOSE:To expand the driving control range with simple constitution while maintaining size reduction by impressing voltage to ferroelectric polycrystalline piezoelectric elements and driving the elements for expansion and contraction in the direction of the support end of a metallic plate, and controlling the tilt angle of a mirror. CONSTITUTION:The mirror 10 for laser light guidance is arranged on the laser light path of an optical communication system. This mirror 10 is fitted to the nearly center part of the beltlike metallic plate 11 which constitutes an electrode and deforms elastically and freely. This metallic plate 11 has both ends supported by fitting bodies and the ferroelectric polycrystalline piezoelectric elements 13a and 13b made of piezoelectric ceramic, etc., are joined with both surfaces between the support ends and mirror 10. The voltage V is impressed between the ferroelectric polycrystalline piezoelectric elements 13a and 13b and metallic plate 11. The metallic plate 11, therefore, twists and deforms to vary and set the tilt angle of the mirror 10. Consequently, the tilt angle is made larger than a tilt angle based upon the expansion/contraction difference between the ferroelectric polycrystalline piezoelectric elements.

Title: Laser length measuring device
Inventor: HIRATA TAKAAKI
IPC: G01B9/02
Filed: 1993-10-19
Abstract: PURPOSE:To provide a length measuring device which has a high intensity modulation frequency and is able to be miniaturized by forming multiple semiconductor lasers that generate beat signal on the identical semiconductor substrate, near each other. CONSTITUTION:The output light on one side of semiconductor lasers 8a and 8b are wave-synthesized by an optical waveguide 9a, so that the beat signal of differential frequency between oscillation frequencies of semiconductor lasers 8a and 8b is generated. The beat signal is made to be incident, through the optical waveguide 9a, a lens 10 and a prism 11, as reflection light, on an optical detector 12. A frequency difference control circuit 13 controls the oscillation frequency of the semiconductor lasers 8a and 8b so that the frequency of beat signal becomes preset value. Its optical path difference causes phase difference from the outputs of optical detectors 12a and 12b. Since the phase difference changes depending on positions of measuring object to which the prism 11 is attached, by measuring changes in phase difference at a data circuit 14 and a control circuit 15, the movement distance of the measuring object is obtained.

Title: Production of oxide superconducting thin film
Inventor: TERAJIMA YOSHIAKI
IPC: C01G1/00
Filed: 1990-09-29
Abstract: PURPOSE:To obtain a superconductor thin film having high critical current density and excellent surface smoothness by subjecting a REM2Cu4O8-delta thin film on a substrate to heat treatment successively in a nonoxidative atmosphere and oxygen-contg. atmosphere at specified temp. CONSTITUTION:A REM2Cu4O8-delta thin film (1-2-4 phases) is formed on a substrate by sputtering, vapor deposition, etc. In the formula, RE is one or more rare earth elements containing Y, M is one or more elements from Ba, Ca, and Sr, delta is oxygen defect with 0<delta<1, and part of RE can be replaced by Ca. Then, this thin film is heat-treated at 580-650 deg.C in a nonoxidative atmosphere to produce REM2Cu4O7-delta oxide superconducting material (1-2-3 phases). If the temp. is lower than 580 deg.C, decomposition of 1-2-4 phases is not effected enough, while at higher temp. than 650 deg.C, smoothness of the film surface is reduced. Then the superconducting material is heat-treated at 400-650 deg.C in an oxygen- contg. atmosphere. Thus, by this heat treatment, the same critical temp. Tc can be obtained for the superconducting material as that of an oxide superconducting material of 1-2-3 compsn prepared by a usual method.
